I stumbled upon a blog post by Diptanshu Singh discussing whether IS-IS flooding in highly meshed fabric is as much of a problem as some people would like to make it. I won’t spoil the fun, read his blog post ;)
The really interesting part (for me) was the topology he built with netlab and containerlab: seven leaf-and-spine fabrics connected with WAN links and superspines for a total of 68 instances of Arista cEOS. I hope he automated building the topology file (I’m a bit sorry we haven’t implemented composite topologies yet); after that all he had to do was to execute netlab up to get a fully-configured lab running IS-IS.
If you have ever used Proxmox, you know it’s a capable and robust open-source hypervisor. When coupled with Ceph, the two can provide a powerful HyperConverged (HCI) platform; rivaling mainstream closed-source solutions like those from Dell, Nutanix, VMWare, etc., and all based on free (paid support available) and open-source software. The distributed nature of HCI […]

Today on the Tech Bytes podcast we talk with sponsor Palo Alto Networks about two new approaches for supporting remote and hybrid workers. First is Okyo Garde, a new wireless mesh product to support remote work. And second, a new bandwidth-on-demand option for Palo Alto’s Prisma SD-WAN.

The steepening trajectory towards event-driven and real-time API architecture is imminent.
Researchers are marveling at the scope and magnitude of a vulnerability that hackers are actively exploiting to take full control of network devices that run on some of the world’s biggest Continue reading
On today's Heavy Networking we talk about why it's important to say "No" when someone tries to put more work on you than you can handle. Guest Tom Hollingsworth wrote a controversial blog post entitled “No Is A Complete Sentence” about how to say "No," to even when it's hard to do. We talk about the nuances of this stance, the risks you take when you do, time management, balancing workloads, and more.

Stuart Charlton did his best to explain the concept of pods in the Kubernetes Networking Deep Dive webinar, but we were still a bit confused. Next step: let’s talk about typical inter-pod traffic scenario.

I joined Cloudflare in March to lead Partnerships & Alliances for Asia Pacific, Japan, and China (APJC). In the last month I’ve been asked many times: “Why Cloudflare?” I’ll be honest, I’ve had opportunities to join other technology companies, but no other organization excited me more than Cloudflare. So I jumped. And I couldn’t be more thrilled for the opportunity to build a strong partner ecosystem for APJC.
When I considered joining Cloudflare, I recall consistently reading the message around “Helping to Build a Better Internet”. At first those words didn’t connect with me, but they sounded like an important mission.
I did my research and read analyst reports to learn about Cloudflare's market position, and then it dawned on me, Cloudflare is leading a transformation. Taking traditional on-premise networking and security hardware and building a transformational cloud-based solution, so customers don’t need to worry about which company supplied their kit. I was excited to learn that Cloudflare customers can simply access the vast global network that has been designed to make everything that customers connect to on the Internet secure, private, fast, and reliable. So hasn’t this been done before? For compute and storage that transformation is almost Continue reading
